If you’re looking for a hearty meal this year, best steer clear of the Anthony household.

In January, Knick superstar Carmelo completed a 15-day fast. Now his better half, LaLa, has dropped 15 pounds off her curvy frame after joining a popular Hollywood diet plan dubbed “60 Days of Fitness.”

“It’s 60 days straight of working out and eating well,” the reality star told The Post. “After seeing his weight and body change dramatically, my curiosity piqued.”

LaLa, 33, is down to 134 pounds and is on day 47.

“60 Days of Fitness” was started by rapper The Game, a friend of LaLa’s, who enlisted her into his ever-growing ragtag group of fitness fanatics that includes fellow reality stars Rob and Khloe Kardashian.

And LaLa’s hooked even if it means taming her milk-chocolate addiction.

“It is my biggest weakness. I’ve found other things that taste healthy like dark chocolate. After a while, you train your taste buds to not want it as much,” she says.

There’s no magic or science behind the movement, which is documented on Instagram. It’s just discipline to eat more healthy and then exercise until you want to hurl. The group meets daily for three-mile runs in Los Angeles’ Runyon Canyon where they mix in lunges, squats and jump squats.

“In the beginning I could barely walk it. I thought I was going to need a wheelchair. Now I’m running more than half of it. It’s the best cardio ever,” LaLa says.

When LaLa is in the Big Apple, she puts on her boxing gloves and trains at the famed Trinity Boxing downtown, where her hubby works out in the off season.

And when it comes to food, LaLa maintains a regular menu of healthy fare.

She eats oatmeal and Greek yogurt for breakfast, a lavash turkey wrap with hummus instead of mayo for lunch, and grilled fish or chicken with quinoa for dinner.

“To get into the 120s would be a dream,” LaLa says. “I haven’t seen them in a long time. But my goal is to get toned.”

She’s careful to note that she isn’t following in the footsteps of her hubby, who famously did a 15-day spiritual cleanse, where he abstained from dairy, carbs, meats, fish and sweets.

Dubbed the “Daniel Fast,” after the prophet, the diet is limited to fruits, vegetables, raw juices and protein shakes. Carmelo, who faces the Celtics tonight at Madison Square Garden, reportedly does the plant-based partial fast every year to get some clarity in his life.

“With him it’s different,” LaLa says. “He’s so disciplined. If there was ever junk food in the house, it was because of me. If he’s splurging, he might have a Starburst.”
